    Question Nested IF statements for Lintel family

    I am trying to make a custom Steel Lintel Family and would like for the extrusion of the angle legs be driven by the Parameter OPENING WIDTH.

    I have most of the family working except the formula portion. I have read on nested IF statements, but I am STILL having issues.

    Right now I have: if (OPENING WIDTH<4', 3 1/2", if (OPENING WIDTH<6', 5"))

    I keep getting the error BAD IF STATEMENT format.

    What I would like to happen is for opening smaller than 4'-0" use a 3 1/2" angle leg and for opening greater than 4'-0" but smaller than 6'-0" use a 5" angle leg. Eventually I do want to add a thir condition to the statement, but if I can't get this to work expanding on it is hard.

    Where am I going wrong? Thanks for the assistance.

    Default Re: Nested IF statements for Lintel family

    IF/THEN/ELSE statements need all three arguments to be valid. Your statement is missing a final ELSE statement, which would be what occurs if no other conditions are met.

    Your formula: if (OPENING WIDTH<4', 3 1/2", if (OPENING WIDTH<6', 5", ELSE))

    All you have to do to correct your formula is enter a value you would like to be returned (as the ELSE argument) if OPENING WIDTH is greater than or equal to 6'.

    Thanks! I will give that a try. That makes sense. This is the first family I have made with nested IF statements.
